DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] By Figures 1 to 6 The present application discloses a defrosting heater assembly, which comprises a heat storage support body 1 capable of storing heat energy, a heating body 2 fixedly arranged at the side edge of the heat storage support body 1 and capable of defrosting, a heat insulation frame 3, a hard aluminum foil reflector 4, a plurality of heat storage balls 5 and a plurality of heat conduction supports 6. The hard aluminum foil reflector 4 is fixedly connected to the side edge of the heat insulation frame 3 and can increase the heat radiation effect and thus improve the defrosting effect. The heating body 2 is fixedly connected to the side of the hard aluminum foil reflector 4 away from the heat insulation frame 3. The heat storage balls 5 are fixedly connected to the inside of the heat insulation frame 3. The heat conduction supports 6 are fixedly connected to the side edges of the heat storage balls 5 and are attached to the hard aluminum foil reflector 4. The heating body 2 is composed of a first insulation mounting strip 7, a second insulation mounting strip 8 and an S-shaped electric heating pipe 9. The first insulation mounting strip 7 and the second insulation mounting strip 8 are both fixedly connected to the hard aluminum foil reflector 4 and can play an insulating role and stably support the S-shaped electric heating pipe 9. The S-shaped electric heating pipe 9 is connected between the first insulation mounting strip 7 and the second insulation mounting strip 8. The S-shaped electric heating pipe 9 is provided with a terminal 10 at both ends, which can be connected to a power line.

[0025] When defrosting, the S-shaped electric heating pipe 9 heats up, and the hard aluminum foil reflecting plate 4 reflects heat, thereby improving the defrosting effect. During the defrosting process, the heat storage ball 5 can store part of the heat energy, and the heat insulation frame 3 can have a heat insulation effect to avoid rapid loss of heat energy. After defrosting is completed, the heating body 2 is closed. At this time, the heat energy is released through the heat storage ball 5, and the heat conduction support 6 can transmit the heat energy to the hard aluminum foil reflecting plate 4, thereby achieving the function of auxiliary heating and avoiding the air conditioner evaporator from frosting again in a short time.

[0026] The side edge of the hard aluminum foil reflecting plate 4 is fixedly provided with a reflecting frame 11, which can assist in reflecting heat energy and improve the defrosting effect.

[0027] Both ends of the heat insulation frame 3 are fixedly provided with two mounting supports 12, and bolts 13 are inserted through the mounting supports 12. The mounting supports 12 and the bolts 13 can install and fix the heat insulation frame 3. The hard aluminum foil reflecting plate 4 is fixedly connected to the heat insulation frame 3 through a plurality of bolts 14. The bolts 14 can install and fix the hard aluminum foil reflecting plate 4 to the heat insulation frame 3. Both ends of the first and second insulation mounting strips 7 and 8 are fixedly provided with mounting supports 15, which are connected to the hard aluminum foil reflecting plate 4 through bolts 16. The mounting supports 15 and the bolts 16 can install and fix the first and second insulation mounting strips 7 and 8 to the hard aluminum foil reflecting plate 4.

[0028] The heat insulation frame 3 is composed of a light high-aluminum heat insulation brick layer 17 and a heat insulation felt 18. The heat insulation felt 18 is fixedly connected to the inner side wall of the light high-aluminum heat insulation brick layer 17. The combined structure composed of the light high-aluminum heat insulation brick layer 17 and the heat insulation felt 18 can effectively improve the heat insulation effect.

[0029] The heat conduction support 6 is composed of a metal sleeve 19, a plurality of connecting arms 20, a metal heat conduction column 21, and a spring 22. The connecting arms 20 are inserted into and fixedly connected to the heat storage ball 5. The metal sleeve 19 is fixedly connected to one end of the connecting arm 20. The metal heat conduction column 21 is inserted into the metal sleeve 19 and is in close contact with the inner side wall of the metal sleeve 19. The spring 22 is connected between the metal sleeve 19 and the metal heat conduction column 21.

[0030] The heat conduction support 6 can have a heat conduction function. The spring 22 can limit the metal heat conduction column 21, so that the metal heat conduction column 21 can be in close contact with the hard aluminum foil reflecting plate 4, thereby improving the heat conduction efficiency. Since the cross-sectional area of the metal sleeve 19 and the metal heat conduction column 21 is small, the rapid transmission of heat energy can be avoided, and the heat energy can be released in an orderly manner.

[0031] The heat storage ball 5 is one of mullite, silica, and magnesium. The heat storage ball 5 is connected to the inside of the heat insulation frame 3 through a heat-resistant adhesive.

[0032] The heat-set glue can improve the stability of the connection between the heat storage balls 5.
